To all' 'whom it ma1 concern Be it known trat PLINY CA'ruocI, a citizenof the United States, residing in the city of Newark, county of Essex,and Sta-te of New Jersey,"have invented certain new and usefulImprovements in Phonographs, of which the following is a full, clear,and

skilled in the art to which it pertains to make,l construct, and use thesame.

The objects of my invention are to make certain improvements inthedetails lin the construction of phonographs, and more particularly, toprovide a feed mechanism whereby sc-called 2-minutc and LlC-minutecylinder records may be reproducedy upon the same v simple and effectivechange in the transmission gears;

to provide simple and effective means for engaging, disengaging, andshifting the record feed; to provide simple and effective means forstarting, stopping, and governing the speed of the device; and ingeneral, to improve the construction, in the' direction of simplicityand reduction of cost of cylinder phonographs.

ln carrying out my invention, I make use of the structures illustratedin the accompanying drawings, o'r `their equivalents.

Figure 1 represent-s aside elevation of the phonograph, and itscontaining box with the amplifying horn and reproducer or sound boxomitted. 'Fig 2 is a top plan view of the same. Fig. 3 is a top planview of the spring motor with the guard removed to show the gear trainsin detail. Fig. Il .is an endlelevation, partly in section, of thespring motor. Fig. 5 is a detail plan, partly in section, of thestarting, stopping, and governing device. Fig, 6 is a detail of therecord feed train for operating a two minute record. Fig. 7 is a detail`ofthe record feed train for operating a four minute record. Fig. S isvan end view of the record feed showin the feed nut in dotted lines asdiscngage from the feed screw.

Similar reference numeralsy refer to like parts throughout.

In thedrawings, l represents the containing case which is yprovided witha cover 2 upcn the under side of which is rigidly secured the base 3 insuch al manner that when said cover 2 is lifted .off the case 1 andinvertedjit may rest upon the case with the operating mechanism exposedas shown in Fig. 1. l

All of the working parts of the machine are mounted upon the base 3 vasshown. The two upright plates 6 and7 are rigidly secured to the base bythe laterally extending lugs 8 and rigidly connected together by thespreaders 9 located at each corner of the plates. These plates 6 and 7serve as bearings for the gear train shaftsjournal holes being drilledthrough them at the proper peints for v'the journals ofthe gear shaftsof said train.

The motor spring winding gears 12 and 13, and' associated parts are vofthe usual type and need no detailed description. The gear train 15, 1e,17, 1e, from thedrive gear to the governor is also of the usual type andneed not be further described than to say that its purpose is toprogressively increase the speed of the gears from the motor drive gear1-1 to the governor gear 21'that the latter will. run at a relativelyhigh speed.

The other ends of thesprings 23 are rigidly secured to the sliding sleeve or collar sleeve 26is provided with a friction disk 27, for cooperation with `theregulating friction brake 28 -the latter being secured to the extremityof a pivoted lever 29 mounted upon the stud 30 as shown in Fig. 5. Theopposite end of thel lever 29 is provided with a stud 31 which projectsthrough an aperture in the side plate 6 where it impinges upon the innerface of the oscillating cam disk 31', the latpivoted to the side plate Gat 32. The cam diskll is provided with a circular cam face 33 graduatedfrom nothing to a maximum so shown in Fig. 4. the cam that in theposition' y face will depress 'of the arrow; the

I may also niark upon the' face of theside plate 6 acircular scale 37 `for coperat-ion with the pointer 35. In this mannerthe tempo and key of a musical selection may be' regulated to suit themusical taste andjudgment ofthe operator; or the tempo may be markedupon the record itself and the pointer set; tothe corresponding numberupon thescale In the upper edges of theplates 6 and `7 rigidlysecuredfthe carrier tubdSSyh- 1n vwhich is secured the sliding; mandrel;shaft 39 carryingjft4 its outer end` th e` `o`werT hangingrecrd'mandr'el'4.'

With the-"late mechanical refine# ments, however,the r'eeord'helices on oy- 'lindrical records have beendoubled, so as'q1-as? vThis woher-farniente;

for the operator Imay haveiaceumulated a 'large number of the 2-mmuterecords which would be useless upon a four-minute mam chine. In order toaccomplish these ends, l journal the screw feed shaft '48,"at one end inthe upwardf projection upon the 'plate 6,

and its other end in the circular lplate 43 so that said feed shaftshall lie parallel Witl1 the sliding mandrel shalt).v IThis shaft isthreaded for the ,greater portion of its length as shown, and hasmounted at lits end 1:

near theplate 6 the broad vfaced gear 49 with the'larger idle 'gear 50the latir beingr mounted. upon the sliding shaft 5\ The gear 53islocated in position 'to meslix. either `with a gear 52- on the shaft53er with a gear 54 ongthe saniesliaft with and adjacent to gear. 17according to whether the sliding shaftfisp'ushed in or pulled out. Thegear 52 .is rigidly mounted on the` shaft 53 and said shaft has alsorigidly mounted thereon the ,freer 52 which lata ter is always in meshwith the gear 16. The button 51' is secured' tothe outer end of a'meansfor sliding it back and forth.

The gear 54-is just double the diameter of the gear 52, so that when thescrew feed shaft 48 is driven through the train 16, 52f, 52, 50 and 49,itlrotates half as fast as when driven throuh the train 16, `17, 50and`49 resulting in feeding the record 'mandrel through 'its entiretravelin' four minutes,

Upon the upper side of the guard 69 is located the pivoted index pointer7l (Fig. 2) Said pointer having a bifurcated rear extension whichextends through vthe aperture 72 and straddles the gear 50 sothat as thelatter is shifted to 'either 2# orA t' minute position the fact isindicated by the pointer 71.A

The spring box 10 contains a valuable improvement in construction. Inphono graphs, it iscommon to mount a pair of springs in tandem upon themain' shaft.; z'. e., one of the springs is connected by `its inner endto the winding shaft and its outer end to the inside of the flange .ofthe corresponding half spring box; the other spring being oppositelydirected is connectedat its outer end to the inside of the flange' ofits half spring box and its inner end to a sleeve mounted upon .thewinding shaft, said sleeve having rigidly mounted upon itf'the main*drive gear such as 14. It has been the'c'ustomto by means of a series ofstraps overlapping the adjacent flanges of the half boxes, eitherriveting such straps or screwing them down upon the flange. lI find thisisboth unnecessary and inconvenient, and my improvement consists inproviding one of the half boxes 75 with a strap 76 riveted down andoverlapping the ange of the other half boX 77, as shown. The` adjacentflange of `the other half-box 77 is provided with a hook 78; which, whenthe two `half boxes are brought together, will engage thel strap 76 andsince .the springs within the box' are always under tension, the hook 78 will always remain in engagement with the strap 76. When it becomesnecessary to separate the half boxes 7 5 and 77 for the purpose ofrepair or otherwise, it is only necessary to remove the spring box andWinding shaft 1l, from the side plates 6 andl 7, twist the half boxes mthe direction of the arrows disengage 4the `halfznut 68 from thev 'feedscrew 48.4v l

for carrying the? amplifying'- driying 'shaft and fasten the half springboxes together' when' the halfbox;75 with its sleeve and the* gear 14-will slide free from the shaft.. I have not illustrated the interiorarrangements of thek springs as itis common with spring l motors where aplurality of springsin tandem arelmounted upon a single wind- :ingshaft. My improvement of the spring box 10 resides wholly in providingthe readily detachable means for connecting the half boxes 7 5 and77. Inpractice, I use two or more of these hooks 76 and-78 upon the halfboxes.

'It 'will be seen that bythe construction illust-rated and described, Iain-able by the simple-insertion of the-sliding shaft 5l with its gear50 `meshing alternately with the gears 52 and 54, both taking theirmotion i rom the gear 16 of the main driving train,

to 'utilize in the same machine bptli the old f2m1nu te records and thenew'Li-minute rec' ords; and that by the -simple governing ldisk' 3V,Iam able to govern the speed of I the motor from stop up to the maximumspeed ofI which the machine is capable. The simple disengaging andshifting device `for the record feed is also 'agreat advantage in.quickly shifting the record for repetition of a Vselection or any(part`t'hereof.
